Question

The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in miles), r is the rate (in miles per hour), and t is the time (in hours). Consider the statements below that describe the driving rates for three people. Graph the equation that represents the rate of the fastest person. Braylon drives at a rate of 50 miles per hour. Kiko drives for 9 hours and goes 405 miles. Presley drives 385 miles in 7 hours.

Answer 1

Answer:

Presley is the fastest

d= 55t

Step-by-step explanation:

d= rt

Divide by t

d/t =r

so we can find the rate

Braylon

50 miles per hour

Kiko

rate = distance/ time

         = 405 miles / 9 hours

          = 45 miles per hour

Presley

rate = distance/ time

         = 385 miles/ 7 hours

          = 55 miles per hour

Presley is the fastest

d =rt

d = 55 t

Remember t >=0 since it is time
